Belew is the second member of Nine Inch Nails to quit since frontman Trent Reznor reconvened the L.A.-based group earlier this year.

Last month bassist Eric Avery pulled out, writing on Facebook that he "got overwhelmed" and that he wanted to "focus on my musical life here in L.A."

Robin Finck, who'd played with Nine Inch Nails previously, stepped in quickly to replace Avery; Reznor hasn't said who (if anyone) will take over for Belew. Minus the guitarist, the band now includes Reznor, Finck, Josh Eustis, Alessandro Cortini and Ilan Rubin.

Late Wednesday evening Nine Inch Nails released "Came Back Haunted," the lead single from a new album to be released Sept. 3. Titled "Hesitation Marks," the disc will serve as the group's follow-up to 2008's "The Slip."
